Powell Elementary School

Merging old and new, the modernization of Washington, D.C.’s Powell Elementary School has shaped a vibrant, green, and healthy learning environment that accommodates the school’s rapidly expanding program. The project combines two new additions and the renovation of a historic brick building through a biophilic approach that bolsters a connection with the cycle of the day and the changing seasons. It also introduces the city to its first-ever solar chimneys.

The project began as a small renovation of the existing historic school, but the team saw a much greater need for the predominantly Latinx school community, which had doubled in size. Fortunately, as the project commenced, President Obama visited the school to raise awareness of the increasing need for quality education. That visit helped the school garner additional funding for two modern additions to accompany the historic building’s renovation.

The two new wings, designed to meet LEED-S Gold standards, add 90,000 square feet to the school’s tight urban site. Their design was guided by four key concepts that contribute to healthy learning environments: outdoor spaces, differentiated learning, daylighting, and fresh air. As a whole, the school is an interactive tool for 21st-century education where engagement with sustainable strategies will encourage a new generation of environmental stewards.

Passive ventilation has been embraced by both students and staff. When the temperature, humidity, and wind speed are right, a green light in each classroom activates, letting the students know to open the windows. As the solar chimneys draw out stale air and replace it with cool air, didactic signage explains the stack effect to students and how they can play their part in environmental stewardship.

The project was planned around two green spaces that offer visual and physical access to the outdoors. Numerous outdoor learning spaces, including natural playgrounds, an outdoor classroom, a green roof, and rooftop curriculum gardens, align with new methodologies in STEM curricula. Exterior stairwells that lead to the outdoor programmatic elements offer students and teachers additional exposure to fresh air between classes.

Spaces inside and outside of the school were designed to accommodate the various ways students learn. The school’s corridors and library feature bay windows with nooks and seating arrangements for small group sessions. Every classroom entrance has bench seating for one-on-one instruction, and the school’s double-height atrium with stadium seating functions as an additional breakout classroom.

The bilingual school not only lifts up its students, but it also welcomes the entire community to its facilities and programming. A critical resource, it draws parents and neighbors to its play spaces and English as a second language classes. To make way for the additions, a beloved community garden was relocated to a hillside across the street, now offering ADA-compliant raised garden beds and stormwater management that prevents erosion.
